Explanation

Two-factor authentication (2FA) adds an additional layer of security to the authentication process by requiring users to provide two forms of identification: something they know (e.g., a password) and something they have (e.g., a physical token or a mobile device). This approach significantly reduces the risk of unauthorized access even if the user's password is compromised.
